Glad I found this website since I was buying these from another website for significantly more money. As long DiscountFilters keep this price I will continue to purchase them. Thank you for good prices!

These filters go behind the electrostatic cells in my upstairs A/C, and I also have pleated filters at both intakes (the "better" paper ones, not the cheap fiberglass ones), so I only need to change these every couple of years.
